“We are currently being assisted by Berkshire Lowland Search and Rescue.

“We have received a lot of enquiries from members of the public offering to help search for Rizkallah.

"While not being able to directly help in our ongoing search we do ask you to help by checking your own properties, gardens and outbuildings and sharing the media appeal with the updated photo with friends and neighbours.

“If you do go out, please make sure you are suitably dressed for the conditions, with appropriate coats and footwear and that you are not on your own, you have with you a charged mobile phone and you have told at least one friend or family member where you are going.

"Anyone who has any information about Rizkallah’s whereabouts is asked to contact police immediately.

"The easiest way to do this is by calling 101 and quoting reference 676 (10/3), or in an emergency please call 999.”

Anyone from Bracknell, Wokingham or Reading, Berkshire who sees Mr Moussah is asked to contact police.
